In a global economy, does it make sense to allow workers to move freely?

Letting people go where the jobs are would improve the lives of millions around the world, some argue. But others say an influx of labor into the richest countries would devalue workers' worth and actually hurt more in the long run.

A group of experts recently took on this question in an Oxford-style debate for Intelligence Squared U.S. They faced off two against two on the motion "Let Anyone Take A Job Anywhere."

Before the debate, the audience at New York City's Kaufman Center voted 46 percent in favor of the motion and 21 percent against, with 33 percent undecided. After the two sides faced off, 42 percent voted in support of the motion while 49 percent voted against — making the side arguing against the motion the winners.
